DRAFT-YOKE FOR RAILWAY-CARDRAFT-RIGGING,

T all whom it may concern:

Be it known that I, STACY B. HASELTINE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and draft -yokes for railway car draft rigging.

The object of my invention is to provide a ;simple draft yoke soconstructed as to permit the ready insertion and removal of the drawbar, and one in which the connecting means between the same maybereached and handled from the front end of the car.

In the drawings forming a part ofthis specificationeFigure 1 is aperspective view of a draft yoke and draw bar, the rear end thereof onlybein shown, embodying my invention; Fig. 2 IS a vertical longitudinalsection through the forward end of the draft yoke and the rear end ofthe draw bar; Fig. 3 is a vertical longitudinal section through the rearpart of the draft yoke; Fig. 4 is adetail showing in perspective oneside of the yoke head, the forward end of the upper member of the yoke,a part of the same being broken away along the central longitudinal linethereof, and showing the forward end of the lower member of said yokeand the taper key, the said' lower member being broken away to show thedepending flange from said lower member of the yoke; Fig. 5 is aperspective view showing in detail the rear end of the yoke; and Fig. 6is a perspective view of the taper key.

In the drawings 7 represents the shank of the draw bar, 8 the buttthereof, 9, 9 oppositely arranged shoulders with which said draw bar isprovided, 10 the draft yoke, the said draft yoke having an upper limb11, a lower limb 12, a rear member 13 dependent from the upper limb 11,and preferably integral therewith. The said upper limb is forwardlyprovided with a gib 14 adapted to engage the upper shoulder 9 of thedraw bar. The said upper member is also provided at its forward endwithlateral depending flanges or plates 15, 15, joined to gether at thebottom and constituting a band Specification of Letters Patent.

to surround the draw-bar, and forming with the said upper limb 11 andthe lower limb 12 of the yoke a box-like hollow head 16 to receive thebutt 8 of the draw bar. The lower llmb 12 is forwardly provided with atransverse lug or shoulder 40 adapted to engage the lower shoulder 9 ofthe butt of the draw bar, and is also provided with a dependingtransverse lug or flange 17, preferably integral with the said limb'12,and preferably provided at either edge of said limb with remforcmgpreferably integral flanges 18, 18. In preferable construction the saiddependmg flange or lug 17 is positioned substantially at a point in thelength of said lower limb 12 coincident with the rear face 19 of thebutt 8 of the draw bar. The said lateral flanges 15, 15 are downwardlyextended at either side of the lower limb 12 of the yoke, and at theirlower ends are joined by a transverse preferably. integral plate 20suitably removed from the lower limb 12 to form a space or recess 21 toreceive the,

key 22. The said transverse plate 20 is in preferable constructionlongitudinally beveled on a line rearwardly converging toward the lowerlimb 12 of the yoke.

In preferable construction the key 22 is rearwardly tapered, theunder-face 23 thereof being suitably beveled to engage against thebeveled face of the said transverse member 20. The said key 22 ispreferably provided on its under surface with a shoulder 24, which,when-the key is in position within the recess 21, is suflicientlyremoved from the forward edge 25 of the transverse plate 20 to permitthe insertion of means to remove said key 22 from the recess 21, as forinstance a pinchbar, should the same be re- -quired. The upper face 26of said key is i'eaf'war'dly'forced into therecess 21 to lift the lowerlimb of the yoke and draw bar into position in the manner hereinafterdescribed. The lower limb I2 of the yoke is detachable from the saidyoke, and is rearwardly provided withmeans to engage the same to theconnecting member 13 of said yoke.

I prefer to employ the means shown in the drawings and described asfollows The said connecting member 13 is provided at its lower end witha rearwardly extending transverse lug 33 adapted to engage within thetransverse groove 34 with which the rear end of said lower limb isprovided. I prefer to form said groove by providing the rear end of saidlower limb 12 with an upturned preferably integral portion 35,

having at its upper end a forwardly extended flange 36. In preferableconstruction the rear face of the connecting member 13 is provided with"lateral reinforcing flanges 37, 37, and the rear end of the lower limb12 is preferably provided with the reinforcing flange 38. It will beunderstood that the pocket 39 'withnn the draft yoke is adapted toreceive a draft gear therein.

It will be app-parent that on rearward movement of-lhedi'aw'bar the buttthereof may slide reaiwardly within the yoke, and on forward movementwill draw the yoke forwardly by reason of the interengagement of thegibs of the. yoke with the shoulders of the draw bar. To remove the drawbar from the yoke when/the draft rigging of which the same are a partare mounted be tween the draft sills of a car the bolt 29 is removed,and the 'key wardly from the hollow head, dropping the forward end ofthe yoke to the lowerportion of the hollow opening of the yoke head,

whereupon the upper shoulder 9 of thedraw bar will disengage from theupper gib 14 of the yoke,and sufiicient space will beprovided betweenthe upper gib and the lower gib 40 of the detachable limb of the yoke topermit the draw bar to be drawn forwardly and removed. Meanwhile a draftgear within the yoke .may remain therein until the draw bar is replaced,as may be desired, or if it is desired to remove the draft gear from theyoke the same may be done by moving the detachable limb of the yokerearwardly, and dropping thesame after the key 22 and bolt 29 have beenremoved. On replacing the draw bar within the yoke the same is passedthrough the forward openin of the yoke between the gibs there of whi ethe detachable member is resting within the hollow head of the uppermember, and thereupon the taper key 22 is 1nserted underneath theforward portion of the detachable limb, and between it and the innerlower face of the hollow? head, and driven into position, thus liftinthe draw bar into position with the shoul ers thereof in engagementbackof the gibs of the limbs ofthe yoke, and the taper key secured 1n po- 7bination, a draw bar, a key, and a draft yoke 22 withdrawn forsition bythrough.
